When i'm syncing my iphone or transfering files via USB. The OS Crawls. It lags so bad that the mouse's movements are affected. Does anyone experience this symptom?
yes. It has been rather consistant. I've originally had a usb hub. But it didn't make a difference. I'm also monitored the CPU usage. It goes between 35% to 84% but it isn't overloaded. Simple programs are running in the background eg. firefox, itunes, msn.
